Be it'kn'own'that 13mm E oitizen'of the United States 'ofAmerioa, reslding in the city of Buffalo; county of *Erie', and State of New Y0rk,' have invented'jcertain new and useful Improvements in Pasteiirizing Apparatus, of w'hichthe following is a full, clear, and exact descrip tion:' "My device relates generally to pasteuriz ing "apparatuses, and more particularly to an apparatus for pastenrizing milk. g One objectjof my invention been toprovide an apparatus in which milk, or other I fluid 'bei'ng pasteurized may 'continu ously pass through? the "apparatus while beingtrea'ted." -j i I 1 -Anotherobject has been 'to 'provide a device in which 'the"n1ilk elements will not separate,"'sinee the milkfdoes not remain stationary'forjany'lengthof time. Fu-rt'hennoreym device isso constructed as to be thoroughly hygienic and provide for an easy and effective cleansing 'ofall the'parts thereof. 7

This :reinforce' ment is formed with a taperedyaperturegin which is; arranged tapered: bushing 36.

This bushing preferably extendsnp to theinner surfaceofthebottom of each pan and has secured toiits'under side a drain pipe 37 which is of sufficient length toiextendxtowa point near ithelbottomwof "the pan below. Rising vertically from :the bushing 36 is a stand: pipe 38, iwhich uis detaehably connect:

These trunnions are. rotatably disposed within bearing brackets 4:3,Wh'e'reby the casing may be suitably tilted for cleansing purposes.

It will be clearly seen thatwhenmilk, or other fluid to be pasteurized, is admitted through :the pipe 31, that it will pass to a point near the bottom of the pan 17 and will then graduallyriseruntil it reaches the top ofthe standpipe 38 of said pan. At this point-it will overflow and pass through this pipe and the drain pipe 37 secured below it,

and into the pan 18 near the lower part thereof whereupon it will again rise in the pan"181 until'it has reached the top of the stand pipe--38 in this pan. The milk will thus continueito travel through the successive pans until it has been raised to thelevel of'the sta'nd: pipe 38 in the lowermostpan from the device; 'or'to clean the same the 21. When itfoverflows into this pipe itwill pass into the funnel 39 anddrain pipe 4.0, whence it' willjbe conveyed to any desired It will be seen that duringr'the operation' ofi; the device, the milkis being continuously passed from one pan .to the other:
